-You get two pieces of dry glass material with perfectly flat faces.
-You press and rub them together. Initially, they seem to glide smoothly against each other...
-...Eventually, after a few strokes, friction force gets very strong until the point you can't rub them at all.
-A this stage the two pieces of glass have become stuck to each other, strongly!
-They will remain stuck indefinitely until you force them apart. You can drop them on the carpet and still remain stuck, you get the idea that this is a very strong attraction, almost like a neo magnet to iron!
-The action does not cause any damage, no scratch, nothing.
-I suspect the action drives all the air out between the glass pieces and outside air pressure takes over??
-I discovered this by accident when I decide to amuse myself with two glass prisms from a pair of binoculars! Any ideas what causes this attraction?
